leak check was 5 to 10% per cylinder, no air escaping through the valves. Fired up and the initial idle will fall off until it dies for about the first 30 seconds of running, then it cleans up, but the idle is never strong. The zinging noise I heard was the power stearing being low on pentosin. That's a break. So here is a video of it running:

00237 - YouTube

At the end you can hear the idle hunt and peck between about 750 and 950 RPM looking for a spot to roost. I noticed there is wind noise in the microphone.

On the windows, and the top. If I push the button for the top latch at the top center of the windshield, they go up. If I release it, they go down. The top has decided that it likes the service position and refuses to move at all. Does anyone have any thoughts on this?

Needs a handover and throttle adaptation.

Thank you Jake, I value your experience and appreciate your advice. I'm hoping the handover and throttle adaptation is something the car will figure out itself as the computer learns who it is again. I figured out the top and the windows, It's a control I have not had use for yet, the parking brake.

If the engine had stored fuel trim from a failing component before, a handover is required to clear it up, because the car doesn't know the engine has been repaired.

To adapt the throttle turn the key on for 1 minute, off for one minute and do that a couple of times, then fire it up and turn on every consumer you can, A/C, rear defogger, all the lights and etc and let it idle.

Check for vacuum leaks and watch the fuel trim.

Thanks for the information Jake. I've followed your advice and have run the car from cold to operating temperaure several times now. It has gone from stumbling and stalling to confident smooth running. the Idle has settled to a rock steady 800 rpm, and there was an intermittant miss, perhaps a sticky fuel injector, that seems completely resolved. The engine now idles confidently, runs smoothly, and revs freely. It's insured and gets plates tomorrow.
